im doing the toyota axles myself on my 88 slamurai. my main reason for doing it is because everyone in truckee wheels with a toyota truck or 4-runner and i found a set of axles pretty easily. im still waiting for my bushings before i go ahead and dive in, but if im able to type with all ten fingers by the time im finished, im sure i'd recommend them.

but if you had the purse and patience for it, there's this guy in reno selling semi truck axles for 400 bucks each...
